Chemical Surface Pretreatment washers are a key component of any surface coating method to achieve lasting, high quality finishes. TF Systems pretreatment washers are used for cleaning substrates immediately before powder, liquid, and electro coating processes. Designed to remove manufacturing oils, dirt, and greases from all types of parts, washers help prepare surfaces for better coating adhesion and greater corrosion resistance.
Depending on your needs, washers are designed as standalone units, or can be incorporated as part of a complete finishing system. Washers range from modest single-stage modules to sophisticated multi-stage systems. All of our washers are custom engineered to meet your specific requirements and built to last with superior components and skilled workmanship.
A pretreatment product we frequently recommend is the recirculating spray washer with continuous overhead conveyor. Due to its efficiency, this type of washer is widely used and offers one of the best options for high volume production cleaning.
This design uses a pump and a network of piping to transfer chemical solutions from the fluid reservoir to a set of risers. Nozzles attached to the risers spray a solution over the parts - that move along via the overhead conveyor - removing unwanted oils and contaminants as a result.
Several advantages of this cleaning method include high production volume efficiency, a reduction in the required chemical concentration, an overall decrease in process times, and recirculating the solution keeps it fresh.
For processes where continuous pretreatment cleaning methods are less than ideal, we recommend a manual spray wand pretreatment approach. This batch, or “stand alone” method uses an electric motor to power a pump. The pump pressurizes the solution and feeds it to a hose through a heating coil, then on to a hand held wand assembly.
In most cases, hand held systems are best suited for cleaning large products, or in custom rinsing processes. Employing this type of system has many advantages, including low capital costs. This system is also advantageous for hard to clean, bulky pieces and in low volume batch processing situations.
Often referred to as dip tank cleaning, this process uses tanks to hold specialized cleaning solutions. Depending on your requirements, parts are normally dipped into the chemical bath one-by-one, or dipped continuously by using an overhead conveyor. Either way, dipping requires an overhead hoist, which lowers individual parts, or baskets of parts into the tanks.
Advantages of using immersion pretreatment systems include low capital outlay and simple maintenance. They are also beneficial when your pieces require prolonged chemical contact and where parts need thorough contact with one or more chemical solution.
